windeployqt.exe file is empty
After a recent Qt 5.12.3 installation:
Under ..5.12.3/mingw73_32/bin, windeployqt.exe exists, but size is 0 bytes (empty)
Under ..5.12.3/mingw73_64/bin, windeployqt.exe is 1560 kb and works fine for deploying when using appropriate kit.
Is this just an installation bug?
It is not a general bug. I got windeployqt.exe in both directories for Qt5.12.3, but I never use them.
Possibly an interference by AV app?
One option is to remove this version and reinstall it.
Are you using the online installer?
That is what I had used for adding both versions.
I reinstalled and the proper file was there. I've concluded that somehow I modified the file after installation, but i don't know how it happened.
Sometimes the antivirus app is removing files. That happened to me in the past.
Good to know that you solved your issue.
